Answer:
A is the anwer 99 degrees
1. (16x² + 48x) ÷ 8x
2. (56x² - 14x) ÷ 7x
3. (20x² - 32x) ÷ 4x
4. (18x² + 15x) ÷ 3x
3y_4=2
3y=2+4
3y=6
y=6/2
y=2
the answer is -7
Step-by-step explanation:
hope this helps
We have the formula S= r * theta , where S is arc length , r is radius , and theta is central angle in radians
So AB= 4 * 45* π/180 = π units
